Hello all,<br><br>Is there a convenient way to only look at deformation field output results for a non-rectangular ROI from the data set? As it is, my input images consist of the structure of interest, surrounded by zero-pixel values, but the deformable registration algorithm still computes how those zero-pixels would be moving. I've seen how to select a rectangular sub-region of an image, but is it possible to choose a non-uniform-shape region too?<br>
